keyboard by playing a note on it, and then enter sequence „# 5” followed by stroke 
of the key that you want to be the top one of the lower part. Since then lower part 
remains at the same channel that was used for whole keyboard, while upper part 
takes settings of upper part, which by default is 5 MIDI channels higher. To change 
MIDI channel, type of event, transposition, or send a Program Change  for split 
part, follow directions described before, regarding non-split keyboard, but now 

changes are made only to the split last played

 before entering the edit mode.

To cancel existing split of a keyboard, as usual play any note on that keyboard, and 
set the split for the top note like this: # 5 <top note>. This sets the end of 1st split 
at the top note, so in fact the upper one is not visible anymore.
Channel and starting note settings of upper split are also used in dual note mode 
described in 5.2.22.

Programming Patch Recall Buttons - #6

Whenever a program/patch/instrument selected from MBBS is often used, it is 
worth to memorize as fast recall button. There can be 64 such buttons, working in 
single MIDI channel. Those buttons can be connected to any keyboard scanner. 
MBBS will send the patch number in channel previously assigned to all those 
buttons with #3 command (see chapter 5.3.). To memorize any patch this way, you 
have to first select this patch somehow by using any method described in chapter 
5.4. Then simply press "# 6", and the key where the patch should be stored. Next 
time whenever you press this key/button, the MIDI Program Change message will 
be transmitted, with the number previously stored.
The number stored this way can only have range 1-128. If last selected program 
was entered with #4 command, i.e. was greater than 128, the number memorized 
will be the one from Program Change part, regardless of actual Bank Select used. 
For example if patch 700 was selected as #4 700, actual number stored will be 700 
modulo 128, that is 60.
To have Program Change memory in multiple channels, you may use multiple 
keyboard scanners or splits, but total number of PC recall buttons must not be 
greater than 64 in entire MBBS system. Also, if 2 or more scanners are used this 
way, the same input in every scanner will generate the same Program Change, 
although in separately defined channel.
